SIT9346

The Endura™ SiT9346 ultra-low-jitter differential oscillator is engineered for harsh environments and is ideal for high-reliability aerospace and defense applications. This device supports any frequency from 1 to 220 MHz in 1 Hz increments and delivers exceptional dynamic performance of 0.23 ps jitter (typ.) and ±10 ppm in the presence of common environmental stressors, such as shock, vibration, power supply noise, EMI, and board bending.

The SiT9346 is 100% screened through the SiTime Endura™ process flow to provide high reliability. 

The device is available in a small 3.2 x 2.5 mm differential package in addition to a 7.0 x 5.0 mm package, and supports all popular output signaling types including LVPECL, LVDS, and HCSL in combination with any voltage between 2.5 to 3.3V.
